Abstract
Reaction of xenon difluoride (XeF 2) and iodine (I 2) or N-iodosuccinimide (NIS) with alkenes gives iodofluoro products in good yields. Aromatics react with XeF 2 and I 2 or NIS to undergo electrophilic aromatic iodination. Iodine monofluoride (IF) generated from XeF 2 is less reactive than IF generated from I 2 and fluorine gas. This difference in reactivity suggests that the interhalogen IF is delivered to the alkene or aromatic from a complex with XeF 2.
